TRANSFERRER FOR WEFT-REPLENSING LOOMS.

Application filed November 111925. Serial No. 68,324.

The invention is designed tor employment in looms of the class in which weft replenishment is effected through automatic insertion ot a reserve bobbin or other weft-carrier or filling-carrier, loaded with weft or lling, into the working shuttle of a loom, with simultaneous ejection of the spent or tailed carrier previously occupying the shuttle.

The invention has relation to the so-ealled transferrers, sometimes termed hammers, by which a fresh or reserve weft or filling-carrier is driven intoa working shuttle with resulting ejection of the spent or tailed carrier. In practice, a transferrer or hammer is constructed with a head-portion which in operation strikes downward upon the top otl the head of the carrier that is about to be placed in the shuttle, and in some cases it is provided with a striker-block that is disposed at a short distance transversely from the said head-portion and arranged to act against the periphery of the wound mass of weit or filling upon the carrier to ensure that the whole length of the carrier, including its tip-portion, shall become enteredfully into the shuttle.

The invention provides in novel manner for mounting a striker-block in connection with the arm of a transferrer or hammer, with facility for adjustment of the said striker-block laterally, so that it may be arranged to strike against the wound mass of weft or filling at the required place in the length thereof, and also with capacity for angular adjustment.

illustrative embodiments of the principles of the invention are shown in the drawings. In the latten- Fig. l shows in side elevation a transferrer or hammer having` an. embodiment of the invention applied thereto.

Fig. 2 is an elevation of the rear end of said transferrer or hammer, loolrimil from the right-hand side in Fig. l, a bobbin loaded with weft or filling, and a portion ot a shuttle, being shown also.

Fig. 3 is a plan view of the parts which are shown in Fig. 2.

Figs. 2 and 8 illustrate the head l and striker-block 2 of a transferrer or hammer in the relations with respect to a bobbin 3 loaded with weft or filling 4- whieh they assume in the operation of driving such bobbin into the working shuttle 5 of a weft-replenishing loom. As indicated in Fig. l, the said head and striker-block are at the rear end of the transterrer-arm G, the said arm c'fending rearward from the sleeve or hub 7 by means of which the transterrer or ham- :r is mounted upon a supporting-stud in loom: rlfhe head l is furnished with a pin 8 proJecting transversely outward therefrom, and striker-block 2 ismmounted upon the said pin.

In the illustrated instance the strikerblock 2 is formed with vertical cheek-portions 21, 2l, and with a recess 22, Fig. 2, between them eXtending from front to rear. Holes 28, Fig. l, are made in said cheekportions, transversely therethrough, these holes accommodating pin 8 and permitting the striker-block to be mounted upon such pin. lllithin the recess is located a stirrnp 9, in this instance annular, encircling the pin 8 and having a screw-threaded upstanding stem 91 which projects above the top of the striker-block, where it receives a washer 92 bridging the recess 22 and resting upon the top ends of the cheek-portions 2l, 2l, of the striker-block, and a nnt 93 contacting with said washer. llfhen the nut is slaclrened ed the striker-block may be adjusted transversely upon the pin 8, toward or from the head l, or may be adjusted angularly by being swung around the pin. vWhen the nut is tightened up, the under part of the stirrup is caused to engage with the underside of pin 8 and the tops oi' the walls of the holes 23 are caused to engage with the top of said pin, thereby clamping the striker-block to the pin in the piace and 'position into which. it has been adjusted.

As will be perceived, the term and arrangement of parts admit oi" being modified more or less without departure Jfrom the essential principles of the invention.

What is claimed as the invention is:

l. rThe combination comprising a transferrer or hammer of a weft-replenishing loom, a pin extending outward therefrom, a striker-block having a hole or holes therethrough occupied by the said pin, a stirrup engaging with the pin, and means combined with the striker-block and the stirrup for tightening the latter against the pin.

2. The combination comprising a transferrer or hammer of a weft-replenishing 100m :L )in extendno outward therefrom a 7 .l C a maker-block havmg eheek-portloils Sepa'- rated by a recess, Wlth holes m sind cheekpornons occupied by Jhe sind pm, a stu'rup occupyuw mi recees, engaging with the pm and excen e pwmd, and means comhmed with he 11m-fard extension and with the nog Oi the Stmke-boen Ier tlghtenmg the smrup against 'the pm and thereby seeming the 10 striker-block in adjueted position.

8. The Combination comprising a transfewer or hammer of a Weft-replenshing 100m, a pin extending outward therefrom, a striker-block hzwng cheeks separated by 2L Ieeess, with holes in said cheeks occupied by said pin, an annulal etl'rup occupying said recess, ene'clng the pin, and having a, screw-threaded Siem, and :L nut applied. to Said stem md adapted to tighten the stil'- rup to clamp *che block in adjusted position on the pin.
